3 Claims. (CL 28228) This invention relates to an improved board meansfor accurately tracing sewing lines and assembling details from garment,millinery or othor clothes making patterns to the goods or fabrics usedfor making the garment or other product so that errors in such tracingmay be avoided, the thread and needle operations now required formarking these sewing and assembling details dispensed with, andproviding inexperienced workers with a simple and accurate means forcontrolling the transfer of the sewing and assembling lines from apattern to the fabric or goods used.

Another object of the invention is to provide a pattern tracing boardwith a marking surface having loosely ing substance and an open meshmaterial disposed against this chalk charged surface so that no transferof the chalk to any fabric or goods will take place when the sections ofthe garment are laid on the boardagainst the mesh material, but willtake place when a marking wheel or similar tracing tool is pressedagainst the pattern attached to the pattern cut sections of fabric orgoods disposed on theinesh material and the sewing and assembling linesof the pattern traced by the wheel or tool will be reproduced upon thebottom side of the fabric or goods.

A further object ofthe invention is the provision of a board withtracing or marking areas charged with differently colored marking chalkso that the garment maker or other person using the tracing or markingboard may use either a White chalk marking surface or a red or brightlycolored marking surface.

With the above and other objects in View the invention comprises certainnew and useful con-- structions and arrangements of parts, clearlydescribed in the following specification and fully illustrated in thedrawings, in which:

Fig. 14 is a detail sectional view of a board having its oppositesurfaces charged with a loose chalk marking substance.

Fig. 15 is a cross sectional view of Fig. 11.

Referring to the drawings which illustrate the practical embodiment ofthe invention, It designates a board constructed with a central orintermediate section II, and outer sections l2 and I3, which areconnected to the opposite sides of the central section I I by means offlexible paper, cloth or leather hinges Ha and I311.

Each of the sections of the board H3 is constructed of fiat materialhaving a working side or face which is absorbent On this working face alayer of marking substance I4 is evenly laid by spraying, by paintingwith brush, by screening or by roller or other action.

The marking substance or material 14 may be composed of finely powderedchalk or calsomine and a binder orsizing adhesive, like casein glue orother similar material, proportioned so that the substance I4 will forma layer of chalk or marking particles which will not separate from thesurface of the board by gravity, but which will be detached in part onlywhen line pressure is placed onthe material disposed against the surfacemarking substance I 4.

To prevent accidental transfer of the marking substance [4 to any fabricor garment sections disposed against the board, a sheet 15 of open meshmaterial or gauze is placed over and against the marking substance; Onlythe outer marginal edge portions of thegauzesheet l5 are secured to theboard. This is done by means of a U- shaped binding strip [6' whichextends along the side and end edges of the board 10, as shown in Fig.1, and across the hinge joints between the sections thereof.

It is desirable thatthe gauze or open mesh sheet l5 be secured underapproximately equal tension so that its threads will not drag across themarking face of the board It when engaged or subjected to the pressureof the tracing or marking tool used. For this purpose one side ofthe'gauze' or open mesh sheet I5 is first seof the board H! inwardly ofthezfoldedzmarginali edges of the gauze or open mesh sheet.

The pattern selected is then placed" against the length of fabric or.goods to be used in making the" garment" and" the pattern pinned alongits outer edges by means of pinsp, or similar fasteners, to the lengthof fabricor yard goods. The fabric or yard goods is then cut out t0conform to the outer'contour" or outline of the pattern.

The board is then placed in open position, as shown in Fig; 1, on atable or other work'supportwith the marking surfaces thereof in upperposition.

The fabric F, with the pattern P still pinned or fastened to the fabric,is then placed in direct contact with the gauze or open mesh sheet l5which spaces it out of direct contact with the marking surface of theboard Q0; The fabric F and th'epattern P should lie as flat as possibleso that no wrinkles will be present.

The sewing lines and assembling" details or other interlineationsof thepattern may then be traced by placing a marking wheel of conventionalconstruction, as indicated in Fig. 12, directed in a. rolling actionover the sewing, tucking, cutting, and other assembling control lines orpoints" of the pattern, or by-using a pencil or pointed stylus, usingsufficient manual pressure to cause the fabric or goods to engage themarking face" of the board I!) through the threads or open spaces of thegauze or open mesh sheet l5. In this way all sewing linesand'assemblingpoi tern may be reproduced on the bottom side of the fabric Fwhich is" attached by the pins p to the pattern P. When linepressure isapplied by a toothed wheel or stylus to the pattern, parallel to or overthe interlinearassembling points of the pattern", the fabric F is forcedinto physical contact with the marking substance of the upper surfaceofthe board It causingthe underside of the fabric or-goods to bemarkedwith grains of the marking substance in a series of dots or' aseries of short dashes, depending on \vhethera marking wheel or stylusis'used.

When all of the: sewing: and? assembling: lines and control points of'the pattern have; been transferred to the" fabric: or: goods the:underside of the fabric or; goodswillcorrespond in every detail totheinformation. and. sewingiandi assembling linesv supplied by thepatt'erm.

When it is: desired to: simultaneously'mark: two sections of a garment,as for'thezright and left sides" of a dress, skirt; b1ouse,.coat; etc.,two lengths of the fabric or goods areattached' by pins to the pattern.and. likewise: cut." out; along the contour; of' the pattern- Theoutermost piece of fabric.- is thenplacedv againstthe. gauze sheet l5with the pattern'uppermost. The. sewing lines andassembling details of'the. pattern are then transferred to" the lowermost; section. of fabricso that it fully corresponds with. the showtracing or other toothed tsof the patlines orsewing and ing on the pattern. The pattern is thenseparated from the two garment sections and the holding pins are used toretain these two fabric pieces in proper relation. to] each other. Themarked sectionis then placed uppermost and the unmarked section placedin direct contact with the gauze or open mesh material. The markingwheel or stylus is applied in line pressure against-the lines andcontrol points previously traced. andtransferred from the pattern to thefirst marked" section. When this retracing and transfer: of: themarkedlines and control points of themarked fabric to the unmarked fabric iscomplete the two sections of the garment will have been accurately andcompletely traced or transferred andwill correspond to the singlepattern and will b'e-readyfor sewing into the required garment.

It is found that open mesh material having mesh openings of about 900 tothe square inch, or less, will give satisfactory service. I do not limitmyself to the type open mesh fabric or' material used; It is understoodthat any type of fabric, textile or wire may be used and this includescotton, linen, nylon, rayon, plastic, silkor paper woven material.

The board Ill folds so that the marking faces of the sections H and I2will fold to outer positions, relative to each other, and the markingfaces of the sections II and I3 are disposed in confronting relations toeach other.

The use of this improved pattern tracing or marking board requires,absolutely, that the marking substance remain stable under all weatherand service conditions and to. separate from the board only when linepressure is applied against the marking substance. The foraminous sheet!5 normally separates the fabric or pattern from the marking surface andthe-grains of this marking substance are only transferred to the'fabricwhen suiilcient line or point pressure is applied to the fabric. or thinsheet material, so that grains of the marking substance will bedetachedfrom the board by frictional pressure.

By'experiment Ihave established that a stable marking surface may beobtained which will not flake-or peel and whichwill retain uniformsurface density for continued tracing of pattern lines upon fabricpieces. Unless there is this stability against flaking and peeling andconsequent loss of marking capacity, any'tracingor marking board.designed. for this servicewill be commercially" and practicably useless:

Moreover, it is important that thegrains of the marking: substancetransferred by this line pressure to the; garment. sections be easilyremoved from the fabric or from the garment after the sewing andassembling lines have served their purpose and the garment completed. Ifthe marking substance contains any grease or: wax the transferred grainswill have a strong binding effect with the fabric and will resistremoval by brushing. The use of wax charged papers for makingcoloredlines on fabric pieces. now leads to many objections againsttheir use in garment making. The wax charged. particles tenaciouslyadhere tothe fibres of the fabric and cannot be removed by'brushing andalso resist removal by washing and by most solvents. The

use of solvents is not practicable on many wash fabrics and on starchedand ironed garments, and in any case breaks down the finish of thefabric. When such particles are red in color they become offensive tothe eye and in all cases mar; the. appearance of thefinished garment.

I have discovered by using plaster of Paris, chalk or calsomine, finelyground, mixed with from three to five percent of casein glue, in finelypowdered condition, or an equivalent animal vegetable glue or adhesivethat a base is provided which, when combined with a correct amount ofwater, will provide a mixture which can be coated on the pattern tracingor marking board. To insure the best results the upper surface of theWork board II) should be absorbent, and the marking mixture then evenlyspread upon the absorbent upper surface of the board by using a finesilk or other screen and a roller or brush for applying the markingsubstance through the screen. Air spraying may also be used. The coatingis sufficient to fill the surface pores of the absorbent side of thework board and to provide a thin layer of loosely adherent grains of themarking substance, which will be detached when line or point pressure isapplied to a receiving fabric placed close to the board, leaving enoughmarking material remaining to permit the operation being repeated aconsiderable number of times over the same area of distribution ortransfer.

The invention may also be applied to a flexible sheet, thin enough to beplaced over and on the fabric with the marking face of the flexiblesheet in contact with the fabric, when subjected to line or pointpressure, but normally spaced by the protective sheet of fabric screenmaterial or the foraminous sheet. In Figs. 8, 9 and 10 I show such aflexible marking sheet, indicated by the reference 20. On this tracingor marking sheet the marking substance of finely powdered and looselyadherent chalk 2| is deposited, as previously described. Over thismarking surface a sheet of foraminous material, as gauze or screen, issecured by its outer edges, so that the major portion of the area of theprotecting sheet 22 is relatively loose, being wholly unattached to thesheet 20. The pattern tissue is placed against the negative side of thesheet and the positive side or the marking surface 2| is disposedagainst the upper side of the fabric, laid on a table or other flatsurface, and then marking is made by a stylus or toothed wheel, aspreviously described.

In Fig. 11 I show a board 25, having a section 26, slidable endwiseunder the screen 21. The upper surface of the board 25 is provided witha white chalk marking surface, and the upper surface of the slidingsection 26 is provided with a red chalk marking substance 28, or anyother suitable contrasting color.

In Fig. 13 I show a board 30, having a marking substance 3| of one coloron one side thereof and a marking substance 32 of another color on theopposite side thereof. A screen or open mesh fabric 33 covers thesurface 31, and another screen 34 covers the surface 32. A flexiblepaper or fabric sheet 35 is attached at 35a. to one side of the board,so that it can be disposed over either marking surface 3| or 32, whenthe board is inverted. In the showing of Fig. 13 this protective sheetis shown disposed under the surface 32, and when the surface 32 would beplaced uppermost this protective sheet would be disposed over thesurface 3|.

My invention provides practical means for accurately tracing andtransferring to garment fabrics the sewing and other assembling detailsand lines of patterns, so that garments of every description can be madeby inexperienced persons and which will correctly follow the stylingplanned by the original designers and producers of the patterns.

My invention also provides practicable means for dispensing with theoperation of stitching tailors tack loops of thread through fabrics toestablish the sewing lines and assembling destraight or correctly curvedstitching lines. Time, labor and material are thus saved and anincentive is provided for making clothes at home because of thecertainty that acceptable garments can be made by inexperienced personsusing my invention.

It is understood that another base for the marking substance other thanhere given may be used, provided that this marking material is combinedwith an absorbent board to provide a loosely adherent marking surfacingmaterial, which will remain stable and resist accidental separation ofthe grains of the marking material and to all transfer thereof exceptonly by line or point pressure on fabrics placed against this materialor substance.

Having described the invention, I claim a new:

1. A pattern tracing device comprising a rigid fiat member having anabsorbent surface, a layer of marking material applied to said absorbentsurface and dried in situ, and a sheet of thin foraminous materialstretched over said marking layer and supported at its edges upon theflat member so that said foraminous sheet, inwardly of its edges, iswholly free from attachment to said fiat member, said foraminousmaterial providing means for spacing the fabric to be marked from themarking layer, yet allowing the fabric to be forced by physical contactto engage the marking layer through the interstices of the foraminoussheet, whereupon the marking material will be detached from the layerand transferred to the fabric by physical pressure, the marking layerconsisting of a finely grained powdered substance mixed with from 3 to5% of a water soluble binder in sufficient water to form a slurry,which, after application to and drying on the absorbent surface, willbond thereto and provide a loosely coherent layer which is stableagainst flaking or peeling under normal handling conditions of thedevice and which marking layer substance can be readily removed from themarked fabric by brushing after such marking has served its intendedpurpose.

2. A pattern tracing device according to claim 1 wherein said finelygrained powdered substance is chalk.

3. A pattern tracing device according to claim 1 wherein said finelygrained powdered substance is plaster of Paris.
